Abstract
A plastic package for dispensing a product in aerosol form having improved crazing resistance and sustainability is disclosed. The plastic package comprises a bottle having a delivery device, a valve to control flow, and a stable plastic package that holds the product when sealed using the valve. In one embodiment, at least a portion of the plastic package comprises PEF.
Description
Technical field
The present invention relates to the plastic wrapping of the product for distributing aerosol form, described packing pack contains PEF and has the resistance to cracking of the improvement that can reduce breakage of packing possibility.The present invention also provides the mode for improving plastics packed sustainability, and it is by comprising PEF, and in packing by increase, the amount of renewable content is carried out.
Background technology
The aerosol bottle that formed by the plastic material new alternative form as metal bottle has been proposed.Plastic Bottle will give the degree of freedom of the following aspect of manufacturers: develop unique container shapes, exploitation transparent container, produce sustainability and reduction manufacturing cost with respect to the improvement of metal.Propose to gather (ethylene glycol terephthalate) (PET) as the plastic material that can be used for aerosol bottle, because it is transparent and can be for can recirculation.But, limonene and other perfume base (prms), and hydrocarbon propellant and other system component are (or in some cases, even just water, there is Different Results according to the pH of water) can be diffused in PET, especially under hyperbaric environment, and reduce its be full of cracks induced stress.Therefore, these chemical substances can cause the PET be full of cracks in neck and the shoulder regions of aerosol bottle, in described neck and shoulder regions, due to existence and the small curvature radius of pressurized propellant, cause stress so tensile stress exceedes be full of cracks.In these regions, be full of cracks is main, more amorphous because described region is tending towards more highly crystalline and the stretch zones of the bottle that the diffusivity of and composition more consistent than PET molecule is lower.The be full of cracks of this PET can develop into and break (especially under higher strain and when being exposed to can cause material that hydrolysis breaks as SYNTHETIC OPTICAL WHITNER time), and cause the integrity issue of aerosol bottle, and there is potentially dangerous: the plasticity aerosol of reduction can cause the bottle of anergy, it can discharge the gas/product being included in wherein out of control, is therefore unacceptable from the viewpoint of Product Safety.
Therefore, still have the needs to aerosol bottle, described aerosol bottle can be formed by the plastic material of renewable circulation, and described plastic material has the better resistance to cracking than PET.

Embodiment
Having these and other basal component of formula for a product of 1 grade or 2 grades fire hazard or limiting factor and stable plastic wrapping describes in detail hereinafter.
Their behavior definition when " stable packaging " is based on and stores 3 months at 40 DEG C.Stable packaging should not illustrate that in the time of described storage visible fades or hazes, or there is the weight loss more than 1.5%, or in given size (, diameter, width, the degree of depth, length or fold height) aspect illustrates more than 2% variation, or breaks or cause boiling liquid expansion steam explosion (BLEVE).Other optional feature of " stable packaging " comprises and does not show be full of cracks and as by the lax stable evidence of the measured enthalpy of dsc (DSC).
Term " plastics " refers to mouldable or moulding in the time of heating in general, and then hardens into any synthetic or organic materials of the shape of expectation, and it includes but not limited to polymkeric substance, resin and derivatived cellulose.
Term " plastic wrapping " refers to the container vessels of the pressurized package being substantially made of plastics.Seal valve and the actuator of packaging can or can be made of plastics substantially.
Term " recyclable materials " refers to the material (that is, can naturally be repaired or supplement within for some time, use compatible something with the mankind) derived from renewable resources.
Except as otherwise noted, all per-cent used herein, umber and ratio are all by the weighing scale of described total composition.Except as otherwise noted, about all content based on active substance of all wt of ingredients listed, therefore they do not comprise solvent or the by product that may be included in commercially available material.
Pressurized compositions of the present invention can comprise following factors, consisting of or consisting essentially of: fundamental of the present invention as herein described and qualifications and as herein described or other be applicable to be intended to any additional or optional member, component or the qualifications for the composition of Mammals consumption.
PEF, especially individual layer PEF do not suffer the be full of cracks problem of use limonene, other prms, propelling agent and other composition that PET suffers.The aerosol bottle of being made up of the blend of individual layer PEF (homopolymer/multipolymer) or PEF and PET or the layered struture of PEF (inside) and PET has and is present in the less be full of cracks of neck and shoulder regions or does not chap completely.
PEF is by furans-Isosorbide-5-Nitrae-dicarboxylic acid (FDCA) and ethylene glycol (EG; Also referred to as monoethylene glycol or MEG) condensation reaction make, it is similar to for the preparation of the condensation reaction between EG and the terephthalic acid of PET.FDCA can be dewatered and be prepared to form hydroxymethyl furfural (HMF) or derivatives thereof by acid by sugar.Then the oxidable one-tenth of these derivatives FDCA.Ethylene glycol can derive from petroleum resources routinely, and it causes sugar that the reproducible PEF of part (75% carbon is renewable resources) or ethylene glycol also can derive from plant to produce complete reproducible PEF (100% carbon is renewable resources).Deriving from sugared EG can be prepared by the following method: sugar-fermenting is produced to ethanol, ethanol dehydration is produced to biological ethane, oxidation of ethylene is produced to biocycle oxidative ethane, and the hydrolysis of biocycle oxidative ethane is produced to biological EG.
Individual layer PEF is for the plastics packed preferred material of the present invention.Individual layer PEF is hydrolyzed the SYNTHETIC OPTICAL WHITNER such as the superoxide of break (being not only be full of cracks) than the more resistance to caustic liquor of PET as caused whole bottle.In addition, individual layer PEF can meet product and the propelling agent loss specification in plasticity aerocolloidal whole necessary storage time, but independent PET can not.
In one embodiment, plastic wrapping is formed by the multilayered structure of polymer materials.Multilayered structure will further produce the improvement of resistance to cracking and increase package life.Preferably, at least one deck of described multilayered structure is PEF.Most preferably, PEF is the material inside in multilayered structure, guarantees resistance to cracking higher in tensile stress lower area.
Not bound by theory, with respect to PET, PEF (homopolymer/multipolymer) is for better barrier properties and the integrity features of solvent and prms such as limonene, water and other chemical substance, may be due to all hydrocarbon aromatic rings than similar terephthalic acid, containing higher polarity and the PET degree of crystallinity higher than PET of oxygen aromatics furan nucleus.These differences between PET and PEF can change PEF and it comprises the interaction between composition, to reduce or even eliminate the be full of cracks in PEF bottle and significantly reduce water and the propelling agent loss in product.Barrier properties, the reduction improving be the key that requires (product/propelling agent) 2 to 3 year storage time that meets plasticity aerosol container to the susceptibility that chaps/break and dimensional stability.
PEF aerosol container can be together with PET recirculation.Alternatively, can set independent recycle stream to PEF.Wish that aerosol container can recirculation, especially in the North America and other developed country that have a large amount of recycle Infrastructure.For example, some states of the U.S. (for example California and Oregon) require consumer products companies that their bottle is made can recirculation.
